Answer 1

修正：

pip uninstall django-test-without-migrations

我猜这是由django-test-without-migrations的旧版本引起的，不尊重Django 1.8中的optparse到argparse更新，所以我后来确定你也可以用以下方法修复它：

pip install --upgrade django-test-without-migrations

Django 1.8：＆＃34; ./ manage.py test＆＃34;因类型错误而失败：不支持的操作数类型 - ：＆＃39; unicode＆＃39;和＆＃39; int＆＃39;
